Emulsifiable liquid or solid solution and method of making it.

To all whom it may concern:

Beit known that I RAYMOND VIDAL, a citizen of the French Republic, and a resident of Paris France, have invented certain new and useful Improvements in Emulsifiable Liquid or Solid Solutions and Methods of Making Them, of which the following is a specification.

It isWell-known that. sulforicinates and 1ssolving certain organic liquids insoluble in water. According to my present invention, the dissolving power of said substances can be increased considerably by using an alkaline compound of castor oil (in concentrated solution), or with the addition of certain aromatic compounds, as specified hereintreating a relatively large amount or quantity of a liquid organic compound (such as, say, oil of turpentine, or petroleum), with a relatively small quantity of a solution of an alkaline compound of castor oil, adding certain aromatic compounds, of which the following are suitable: phenols, cresols', naphthols.

A soap of castor oil may be prepared by treating 7 5 kilograms of castor oil with 10 kilograms of caustic soda and 100 liters of water, and this liquid soap, or soap solution, will dissolve two and a half times its volume, of the organic liquid compounds to which the invention is applicable, for instance petroleum, or oil of turpentine mentioned above, or in general, any one oi the following liquid organic compounds:

(1) Aliphatic hydrocarbons and their bromin or chlorin compounds, such as chloroform, ethyl chlorid, and light or heavy petroleums of the series O H (2) Cyclic hydrocarbons, light or heavy etroleums of the series C H essential oils. ionone, terpinol, ethyl chlorids or ethyl bromids.

(3) Aromatic hydrocarbons, such as benzols, toluols, xylols, ethyl benzols, cymene, and someof their nitro compounds, such as nitrobenzol.

(4) Aldehydes, ethers, or oxids, whether aromatic, cyclic, aliphatic, or mixed.

5 Pyridic and quinolic bases.

' 6 Tars, empyreumatic oils, such as oil of'cade, oil of birch, and Dippels oil (bone ihe addition of the aromatic compounds (phenols, cresols, naphthols) may be made Specification of Letters Patent,

ity of the solution obtainedand decrease its thickness or v1scosity, and further, such addition enables me to var within wider limits, the proportion of the compoundto be dissolved, relatively to the solution of the alkaline castor oil compound, than if this Patented June 12, 191 '1'.

Application filed July 8,1912. Serial No. 707,548.

. either. to theorganic compounds to be' dislatter compound is used without the additionof aromaticcompounds. When the and matic compounds are not added, the resulting solution is solid or very thick-or viscous. By adding the aromatic compounds, the liquidity of the resulting solution is greatly increased;

Example I: 5 kilograms of naphthol are dissolved by heating with 100 kilograms of oil of turpentine (very dry) and then I add 50 kilograms of a solution of castor oil soap, whichmay be prepared as described above. The mixture is stirred, and the result. is a transparent, thick or viscous liquid which,

becomes slightly colored when exposed to the v air.

The naphthol may case-the resulting so ution remains colorless,

and in which case also the mixture ofspirits be omitted, in which i of turpentine with a solution of castor 'oil soap should be prepared cold, a moderate degree of heat being applied after the mixture has been prepare The liquid solutions obtained according to my invention as described aboveyield very permanent milky emulsions when mixed with water, and a certain quantity of alcohol may be added, without disturbing the character of the emulsion, to produce dilute alcoholic solutions.

Various modlfications may be made,-and

equivalents employed, without departing from the nature of my invention as defined in the appended claims.

,I claim: v

1. A clear solution, emulsifiable with wa- .ter,-containing an aqueous solution of. an alkaline compound of castor oil, a hydroxylated aromatic compound and at least an equal amount of an organic liquid insoluble in water.

2. The herein described process of making clear solutions emulsifiable with. water,

which consists in treating an-organic compound insoluble in water with a solution of an alkaline compound of castor oil in the presence of a hydroxylated aromatic compound, the quantity of said organic comound being at least equal to that of the al- 5 aline compound of castor oil.

3. The herein described rocess of making clear solutions emulsifia 1e with water,

" which consists in mixing and heating together, a solution of an alkaline compound of castor oil, the organic com ound insoluble i
